SPECIFICATION forming part of Letters Patent No. 540,901, dated June 11, 1895.

Application filed February 27. 1892. Renewed December 8, 1894. Serial No. 531,283. (No model.)

To all whom it may concern/.

Y invention.

Be it known that 1, DAVID BROOKS, Jr., a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania,-have invented a new and usefulImprovement in Electric Railways, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in electric railways embracing a novel construction of a conductor, and means substantially as hereinafter described for preventing injury to the entire railway in the event of a short circuit.

Figure 1 represents a transverse vertical section of an electric railway embodying my Fig. 2 represents a longitudinal vertical section thereof. Fig. 3 represents a perspective view of the construction of the railway at the place of crossings.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a sub-way or conduit of suitable construction, and B designates the slot in the crown or top thereof.

O designates insulators within the conduit, the same being formed of suitable non-conducting material, and supported on curved hangers D, which are properly connected at their ends with the upper portion of the conduit and provided with threaded openings in their bases to receive a threaded bolt E, whose u pper end is secured to said insulators, whereby the latter may be properly adjusted in a vertical direction, and applied and removed as desired. On said'insulators are supported the electrical conductors F and G, between which isa strip Hof wood or other insulating material, it being noticed that the'lower con ductor F is continuous, and the upper conductor G in sections separated one from another. At the ends of the sections are pieces J of fusible material, thesame connecting the conductor F with said sections, by which provision, should any material or article drop separatedat the crossings and the ends of the opposite conductors are connected by brackets K, K, said brackets crossing, and being located one below the other, so as not to inter- .fere with each other, and serving to sustain the ends of the conductors, and also to make electrical contact from one conductor to the other, for a brush L.

The ends of the conductors G are tapering so that the brush after passing the end of one conductor may conveniently contact with the opposite conductor.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. An electric railway, having a conductor formed of two conductors with insulating mateiitl between the same, one conductor being said sectional conductor to said continuous conductors, said parts being'combined substantially as described.

3. An electric railway having an electric conductor consisting of a continuous conductor, sectional conductors and insulating material between said continuous and said sectional conductors, and pieces of fusible material electrically connecting each of the sections with the continuous conductor, said parts being combined substantially, as described.

4. Inan electric railway, a'conduit, hangers,

adjustable insulators, continuous and sectional conductors supported on said insulators, insulating strips between said conductors, fusible pieces at the ends of said sections of the sectional conductors electrically connecting them with the continuous'conductor, substantially as described.
